Add directive __SIMPLE_DEVICE__

The tests for __PRE_RAM__ or __SMM__ were repeatedly used
for detection if dev->ops in the devicetree are not available
and simple device model functions need be used.

If a source file build for ramstage had __PRE_RAM__ inserted
at the beginning, the struct device would no longer match the
allocation the object had taken. This problem is fixed by
replacing such cases with explicit __SIMPLE_DEVICE__.
